` d mica i7@ or other sul@ terminates slightly below the cock 25.

this means there is always left in the upper connection between the heating wires and iron tube 17.- The porcelain cylinder and iron tube are so proportioned that the cylinder may be readily drawn out of the tube and byA reason of this construction it is not necessary to drain the radiator before Withdrawing the porcelain cylinder. The other opening 16 is provided with an externally threaded plug 18 haviiign a hollow inner end 19 which receives the closed outer end oit the tube 17. The threaded open end ot the tube 17 which is screwed into one of the openings 16 projects through that opening and on. the outer end oi the tube is screwed a closing cap 20. Extending centrally through' the cap 20 is the bushing 21 through which enter the Wires 22 which are wound around the cylinder 17 These Wires lead up to an adjustable thermostat 23 secured to the upper part of the radiator so that the heating of the element in the bottom ot the radiator may be automatically controlled by alternately breaking and closing the electric cir` cuit by means of the variation of temperature Within the room. @ne of the radiator sections is provided at its bottom end with a suitable drain plug 24and one of the end sections 10 is provided with a lower draincock 25 and an upper drain-cock 26, these being located respectively at the height of." the water when steam is to be made in the radiator and at the height of the Water when the' heat from hot Water is to be used. One of the radiator sections is also provided with a pair of spaced openings 27 and in each or' these openings 27 is screwed a bushing 28 provided on its outer end with a cap or closure 29. Depending from each of the bushings 28 is a filling tube 30 and one ot these tubes terminates at its lower end slightly below the cock 2G, While the other By part of the radiator an air space which con stitutes an expansion chamber since thebradiator cannot be filled through either tube to a height much Agreater than the bottom ot the tube.

There is also providedat the upper part ot' the radiator a plug or bushing 81 having' a cap 32. This arrangement provides an air vent which being loosened slightly allows vfor theescape ot air and later, it so desired,

a very slight adjustment can 'be maintained :tor allowing;r the steam to escape, thus preserving the proper humidity of the atmosphere in the room.

At 33 is shown a suitable term of safety valve so that in case the pressure becomes too great in the upper part ot the radiator the valve will lift and permit the escape of the compressed air or steam from the compression Chamber.

At suitable points on the radiator ranged transparent sight openings t,

re arwhich Locarno are provided with flanges 35 surrouncling` them so that a glass plate 36 may be held therein by a suitable ring 37 secured by the screws 38.

rlhe insulating support for the resistance wire may either have the fiat grooves 39 as shown in Fig. 7 or the square grooves 4() as shown in 8, these grooves being to acconnnodate either or round wire as clearly indicated those figures,

In the iorm of' the device shown in Figs. et and 5 the invention varies somewhat 1nasmuch as the supporting member for the heating element constitirtes` the tie orbond between the outer sections of the radiator. 1n this forni7 and to this endthe outer sections of the radiator are provided with openings el and 4:2 respectively. 'lhe opening 41 is smooth and in thissniootl'i opening is tted a hollow cap i3 threaded interiorly to receive the threaded and closed end of the iron tube fill. rthe other end of the tube is threaded but is open and is screwed. into the hollow bushingt which e is in turn screwed into the opening 42. A cap 20 is secured to the bushing 43 to cover the openingl i2 by means ci? screws or other suitable iasteningjs e5., only one of which astenings is shown. will thus be seen that by screwing up the cap i3 which swivels in opening); 4:1 the parte may be drawn tightly together as the tube M will be placed under tension by compressing the sections.

ln lligs. 9 and l'l'is illustrated a slight modification wherein at the closed end of the tube 17 are provided rates or ports 46 within the cap or bi'ishinf;` which swivels on. tube 17 to support the same and so that Water flowing into the. hollow cap or bushing 47 through the valve 4.8 may pass into the in'- terior of the radiator. ly means of this arrangement the device may be connected directly to the water pipe or mains oi` the buildii'ig or other place where the radiator may be installed, for convenient and speedy filling or drainingl of the same.

ln either et these Ltorins as herein described it is to be noted that the electric heatingr element is a unitary structure which can readily be remos/ed from the radiator, without the radiatorbeing drained, by simply removing` the cap 20 at the end of the tube. l't also to be noted that the sight opening provides a register for determining` whether the water in the radiator is at the proper height with respect to the gage-cock and Yfeed pipe, sin the hcig t of the water can be readily observed through the glasses.

There has thus been provided a simple and eliicient device oi the kind described and ot the character specified.

llt will be obviousl many: minor changes may be made in the 'form and construction ci' this invention lwithout dcpartends of the support extending entirely through the end sections, caps secured to the projecting ends of said support, an elec tric circuit, an electric heating element car ried by said support and connected to said circuit, and a thermostat connected in said circuit to intermittently make and break the circuit and thereby maintain a constant heat Within the room Without a constant current.

14. A radiator provided at its lower portion with a heating chamber having alined openings, a hollow cap fitted in one of said openings, a heating` element support having; one end engaged in said hollow cap and the other end projecting through the remaining opening, and a hollow cap attached to the projecting end of the heating element support. l

l5. ln a device of the character described, a radiator body having alining openings at the opposite ends thereof5 one et said open` ings being' threaded, a bushing externally threaded for a portion of its length and engaged in the 'threaded openings at 'the end oif said radiator body, said bushing being; 2 open at both ends and internally threaded, e tubular casino; removably engaged at one end With the internally threaded portion of said bushingand extending; Within the opening at the opposite end of the radiator body, a heating;1 element carried Within said casing, and a can secured to said op ended bushing.
